Product details
Overview
54FCT16245ATEB from Integrated Device Technology (IDT) is a military-grade 16-bit bidirectional transceiver built in 0.5 µm CMOS, operating over –55°C to +125°C at 5.0 V ±10%. It supports synchronous bus-to-bus communication with dual 8-bit or unified 16-bit configuration, 32 mA high-drive outputs (IOH), 64 mA sink capability (IOL), and power-off disable for live insertion. It is used in rugged backplane interfaces and military data acquisition systems.
For engineers reviewing the 54FCT16245ATEB datasheet, 54FCT16245ATEB pinout, 54FCT16245ATEB application, or 54FCT16245ATEB equivalent, key selection criteria include military temperature compliance, output skew < 0.5 ns, TTL-compatible inputs with hysteresis, and CERPACK packaging for high-reliability board-level integration.
Technical Context
The 54FCT16245ATEB implements two independent direction-controlled 8-bit transceivers via dedicated xDIR and xOE pins per side. Its dual-metal CMOS process enables low-power operation (ICCL ≤ 500 µA) while maintaining fast propagation delays (tPLH/tPHL ≤ 7.5 ns max) and tight output skew (tSK(o) ≤ 0.5 ns).
All I/O pins feature hysteresis (VH ≥ 100 mV) for noise immunity, and output buffers support power-off disable (IOFF ≤ ±1 µA at VCC = 0 V), enabling hot-swap capability in backplane driver applications without signal contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5.0 V ±10% - ensures compatibility with legacy 5 V TTL/CMOS logic rails and stable operation across military temperature extremes. |
| Operating Temp | –55°C to +125°C - qualified per MIL-STD-883 for deployment in avionics, defense electronics, and space-qualified subsystems. |
| tPLH / tPHL | ≤ 7.5 ns (max) - guarantees deterministic timing in high-speed synchronous bus bridging with minimal latency impact. |
| IOH / IOL | –32 mA / +64 mA - drives heavy capacitive loads (e.g., >100 pF backplanes) and interfaces directly with legacy TTL without level-shifting. |
| tSK(o) | < 0.5 ns - minimizes skew-induced timing violations when routing parallel data paths in synchronized multi-bit transfers. |
| VIL / VIH | ≤ 0.8 V / ≥ 2.0 V - provides robust noise margin against ground bounce (VOLP < 1.0 V) and ESD transients (>2000 V HBM). |
| Power-off Leakage | IOFF ≤ ±1 µA at VCC = 0 V - enables safe "live insertion" into powered backplanes without bus contention or latch-up risk. |
Pinout & Package
54FCT16245ATEB is supplied in a 48-pin CERPACK (ceramic flatpack) package, designed for hermetic sealing and thermal stability in harsh environments. Pin assignments follow dual 8-bit transceiver topology with separate direction and enable controls per side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction Control Inputs (Active HIGH) | Determines data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A; overrides only when xOE is active. |
| 1OE, 2OE | Output Enable Inputs (Active LOW) | Disables both A- and B-side outputs simultaneously into high-impedance state; takes precedence over xDIR. |
| 1A1–1A8, 2A1–2A8 | Side-A I/O Ports | Bi-directional data terminals for first and second 8-bit banks; internally buffered with hysteresis and drive strength control. |
| 1B1–1B8, 2B1–2B8 | Side-B I/O Ports | Bi-directional data terminals mirroring Side-A; electrically isolated but share VCC/GND domains within same package. |
| VCC (Pins 5, 11, 20, 24, 33, 40, 44, 47) | Power Supply | Multiple distributed VCC pins reduce IR drop and improve noise rejection across wide ceramic body. |
| GND (Pins 3, 6, 9, 12, 15, 18, 22, 25, 28, 30, 36, 39, 42, 45) | Ground Reference | 14 dedicated GND pins ensure low-inductance return paths critical for clean switching in high-speed military backplanes. |
Key Features
| Feature | Design Value |
|---|---|
| Military Temperature Qualification | Qualified per MIL-STD-883 Class B - enables use in flight-critical avionics, missile guidance, and ground vehicle control systems. |
| Live Insertion Support | Power-off disable (IOFF ≤ ±1 µA) allows safe hot-plug into live backplanes without disrupting system operation or damaging adjacent components. |
| TTL-Compatible Inputs with Hysteresis | VH ≥ 100 mV improves noise immunity on long traces or noisy chassis grounds - essential for industrial/military EMI resilience. |
| High-Drive Output Buffers | –32 mA source / +64 mA sink capability eliminates need for external bus drivers in high-capacitance backplane designs. |
| Low Output Skew | tSK(o) ≤ 0.5 ns ensures simultaneous edge alignment across all 16 bits - critical for setup/hold timing closure in synchronous data capture. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 54FCT16245T | No "A" speed grade: slower max tPLH/tPHL (7.5 ns vs. 4.9 ns for AT variant); identical CERPACK package and military temp rating. | Lacks optimized propagation delay for ultra-low-latency interconnects; suitable for cost-sensitive legacy upgrades where timing margin exists. | Select 54FCT16245T only if design tolerates higher worst-case delay and does not require the tighter 4.9 ns spec of 54FCT16245ATEB. |
| SNJ54ABT16245FK | TI ABT-family part in same CERPACK-48; higher drive (–64 mA/+64 mA), no hysteresis, different AC specs (tPLH ≤ 4.5 ns), MIL-PRF-38535 certified. | Requires external noise filtering due to lack of input hysteresis; preferred in NASA/DoD programs mandating ABT lineage and QML-V qualification. | Choose SNJ54ABT16245FK when ABT compatibility, QML-V certification, or symmetric ±64 mA drive is required - not a drop-in replacement for 54FCT16245ATEB. |
Compared with 54FCT16245T and SNJ54ABT16245FK, the 54FCT16245ATEB delivers optimal balance of low skew (≤0.5 ns), integrated hysteresis, and verified 4.9 ns propagation delay - making it preferred for new designs demanding precision timing and noise resilience in military backplanes.

FAQ
What is the maximum operating temperature range for the 54FCT16245ATEB?
The 54FCT16245ATEB is rated for operation from –55°C to +125°C, fully qualified per MIL-STD-883 for military applications. This range is validated across all electrical parameters including propagation delay, drive strength, and leakage current - ensuring reliable performance in jet engine bays, desert-mounted radar systems, and space-qualified payloads where thermal extremes are routine.
Does the 54FCT16245ATEB support live insertion into a powered backplane?
Yes, the 54FCT16245ATEB supports live insertion via its power-off disable feature: when VCC = 0 V, IOFF remains ≤ ±1 µA on all I/O pins, preventing bus contention or latch-up. This behavior is explicitly tested and guaranteed in the datasheet, enabling safe field-replaceable module swaps in deployed military and avionics systems without powering down the entire chassis.
What package type is used for the 54FCT16245ATEB?
The 54FCT16245ATEB uses a 48-pin CERPACK (ceramic flatpack) package - a hermetically sealed, leadless ceramic package with gold-plated leads. It is specified in the IDT ordering guide as "PVG" option and is designed for high-reliability applications requiring moisture resistance, thermal stability, and radiation tolerance in aerospace and defense deployments.
How does the direction control logic work on the 54FCT16245ATEB?
The 54FCT16245ATEB features two independent direction control inputs: 1DIR and 2DIR. When 1OE or 2OE is LOW, the corresponding 8-bit bank routes data from Side-A to Side-B if xDIR = HIGH, or Side-B to Side-A if xDIR = LOW. If xOE is HIGH, both sides enter high-impedance regardless of xDIR state - providing deterministic three-state control essential for shared bus arbitration.
Is the 54FCT16245ATEB pin-compatible with commercial-grade FCT16245 variants?
No - while the 54FCT16245ATEB shares identical pinout and function with industrial variants like 74FCT16245AT, its CERPACK package has different mechanical dimensions, lead finish, and thermal characteristics than SSOP/TSSOP packages. PCB layout must be specifically designed for the 48-pin CERPACK footprint; no adapter or footprint reuse is supported without mechanical redesign.
